Referring to FIGS. 1 and 2, a constant temperature and humidity machine of the present invention is provided. Such constant temperature and humidity machine may be employed for automatically adjusting a room temperature and humidity level according to a detected temperature and humidity level in the room, detected by the machine. For example, a user may input a desired temperature and humidity (or moisture level) on the constant temperature and humidity machine. Such machine may then automatically adjust the room temperature and humidity levels to the desired levels by dispersing heat or providing a cooling effect, as well as modify moisture levels. In this manner, the constant temperature and humidity machine may modify the temperature and humidity within a room depending on the desired settings relative to the detected temperature and humidity within the room or given area which the machine sits. The dispersal of heat by the constant temperature and humidity machine may be provided with air flow over a heating element, such as silica tubes 21, which also may be in combination with a fine mist mixed with air to modify the humidity or moisture levels in the room. The cooling effect may be provided with a cooling element with, for example, air flow as well as in combination with a generated fine mist provided by the machine. The generated mist of the present invention may be provided with an ultrasonic mistorizing device 24 along with other components described herein, generating the fine mist with optimal droplet sizes that when mixed with air, the mist can provide an improved cooling effect and modifies the humidity and temperature in the room to desired levels.

Now with reference to FIGS. 1 through 4, the constant temperature and humidity machine may include a housing 1. The housing 1 may include a front cover 2, a back cover 3 and a top cover 4. The front cover 2 and the back cover 3 may be coupled together with a clamping arrangement under the top cover 4. The front cover 2 and the back cover may include side walls extending perpendicularly or transversely from the front and back sides of the front and back covers 2, 3 so that when assembled the housing defines an internal cavity therein for housing the various components of the constant temperature and humidity machine. In one embodiment, a bottom surface of the mistorizing device 24 may define the bottom side of the machine. In another embodiment, the housing may also include a bottom side or bottom housing.

The front cover 2 may define an air outlet 5 disposed at an upper portion of the front cover 2. Further, the front cover may define a plurality of air outlet holes 6 disposed at a lower portion of the front cover 2. The back cover 3 may define a first air inlet 7 disposed at an upper portion of the back cover 3. In addition, the first air inlet 7 defined in the back cover 3 may be sized to hold or receive a first air inlet plate 8 such that the first air inlet plate 8 may be installed in the first air inlet 7.

The top cover may define a first installation hole 13 and a second installation hole 14, each disposed on the top cover 4. The first installation hole 13 may be sized and configured to receive a key circuit board 15 so as to be installed in the first installation hole 13. The second installation hole may be sized and configured to receive a display circuit board 16 such that the display circuit board 16 may be installed to be positioned in or adjacent to the second installation hole 14. The key circuit board 15 may be sized and configured to receive input data from a user. Such input data may include temperature and humidity settings desired by the user. The display circuit board 16 may be sized and configured to display input setting from the user and/or display current local temperature and humidity data, and/or any other displayed data that would be helpful for a user while operating the machine, such as the operating conditions of the machine.

The housing 1 may define the internal cavity for housing additional components of the constant temperature and humidity machine. For example, the constant temperature and humidity machine may include a dual air duct 17 that may be installed in the inner cavity of the housing 1 such that an outlet opening of the dual air duct 17 may be positioned adjacent the air outlet 5 defined in the front cover. At the air outlet 5, an oscillating air grid 19 may be coupled to the front cover 2 or be coupled to the outlet opening of the dual air duct 17. The oscillating air grid 19 may be controlled by a motor, such as an oscillating air synchronous motor 18, at the outlet opening of the dual air duct 17. Such oscillating air synchronous motor 18 may oscillate at one or more speeds so as to disperse air from the dual air duct in various directions in the room. Further, the oscillating air synchronous motor 18 may be electrically coupled or connected to a power control board 20. Such power control board 20 may be employed to electrically control, activate, and de-activate various components of the constant temperature and humidity machine, as further described herein and as known to one of ordinary skill in the art.

The temperature and humidity sensor 23 may be electrically coupled or connected to the power control board 20.

Further, the constant temperature and humidity machine may include a mistorizing system that may include a mistorizing device 24, a water tank 25, a mistorizer 26, a small fan 29 and a mist duct 28. The mistorizing device 24 may be positioned at the bottom or lower portion within the internal cavity of the housing 1. The water tank 25 may be positioned or installed directly on the mistorizing device 24. The power control board 20 may be installed on the water tank 25. Upon the mistorizing device 24 being activated, the water at the top of the water tank 25 is supplied to the mistorizer 26, the mistorizer 26 being electrically connected with the power control board 20. The small fan 29 or mistorizer fan may be electrically coupled or connected with the power control board 20 and positioned or disposed at the bottom of the mistorizer 26. With this arrangement, the mistorizer 26 delivers a mistorizer-generated mist upward from the mistorizer 26 and through the mist duct 28 coupled to the mistorizer 26. As the mist is delivered through the mist duct 28, mist then can disperse through a plurality of mist holes defined in a side wall of the mist duct 28.

At certain ultrasonic frequencies, the mistorizing device 24 may be sized and configured to generate the before discussed mist. In one embodiment, the mistorizing device 24 may vibrate to generate water droplet sizes that provide an optimal cooling effect, the ultrasonic frequency to produce optimal vibration and, thus, optimal droplet size may be in the range of 1.0 to 1.7 megahertz (MHz).

When operating the constant temperature and humidity machine, function keys on the key circuit board 15 may be pressed to control the operation or functionality of the constant temperature and humidity machine such that the display circuit board 16 may display the operating conditions of the constant temperature and humidity machine as well as the current conditions of the room. In this manner, as the dual fan 22, the silica tubes 21, the mistorizer 26, the oscillating air synchronous motor 18, the small fan 29 and the temperature and humidity sensor 23 are electrically connected with the power control board 20, such components and their respective operations may be automatically controlled by microcomputer chips on the power control board 20, based on changes to the temperature and humidity in the room, so as to ensure constant temperature and humidity as desired by the user.

When the constant temperature and humidity machine is operating under manual adjustment, a user can press the keys on the key circuit board 15 to turn on the dual fan 22 to cool the room, and/or turn on the silica tubes 21 to heat the room, and/or turn on the mistorizer 26 to increase humidity in the room.
